Taz,

Looking at your profile, starting 3-4 months ago, it's seems about time you hit a normal plateau (normal for my size, and you're fairly similar in terms of goal). Don't fret, hang tough, do what you've doing, and in my case plateaus take 2-3 weeks, and the progress should continue.

Make sure you take measurements, and don't be at 0-carbs, there's no need to. If you really suspect you're doing something wrong, list your daily food intake for a few days, we might spot something you're missing.

Congrats on the loss so far, and remember the last few pounds are the hardest.

Wa'il
